ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to louvered window assemblies and, more specifically, to a louvered window insert having a telescoping frame and louver blades which would allow an installer to easily adjust the width of the insert to that of a window sash by placing it inside an open window and sliding the opposing frame ends outward until the sides of the louver frame are flush against the side jambs of said window and then closing the window until it sits atop the assembly. The telescoping louvered window insert comprises a first frame section having an upper horizontal member and a lower horizontal member connected to one another at one end by a vertical member having a plurality of horizontal louver blades fixedly or pivotally attached thereto with the distal end of each louver blade having a recess or cavity that extends longitudinally therethrough and a second frame member having louver blades of a size sufficient to slide securely within the recesses or cavities of the corresponding louver blades of the first frame sections. The horizontal members of the first frame section have retaining cavities or recesses to receive the horizontal members of the second frame section thereby allowing the width of the entire assembly to collapse or expand as needed within limited parameters. The present invention will provide windows with elemental protection when ventilation is desired and can be easily removed and installed in various sized windows as needed. The present invention could also be fabricated of a translucent or transparent material so as to provide the passage of light through said telescoping louvered window insert.
2. Description of the Prior Art
There are other louvered assemblies designed for windows. Typical of these is U.S. Pat. No. 3,968,738 issued to William A. Matzke on Jul. 13, 1976.
Another patent was issued to Mitsuo Nagase on Nov. 19, 1976 as U.S. Pat. No. 3,991,533. Yet another U.S. Pat. No. 4,064,670 was issued to Roger A. Lichtenwald on Dec. 27, 1977 and still yet another was issued on Aug. 1, 1978 to Robert W. Olsen as U.S. Pat. No. 4,103,468.
Another patent was issued to James Sterriker et al. on Jun. 5, 1984 as U.S. Pat. No. 4,452,024. Yet another U.S. Pat. No. 4,951,728 was issued to Kouichi Takano on Aug. 28, 1990. Another was issued to Anderson Hailey on Apr. 20, 1993 as U.S. Pat. No. 5,203,394 and still yet another was issued on Oct. 11, 1994 to Shinji Tamikawa as U.S. Pat. No. 5,353,565. One other patent was issued to James C. Aarness as U.S. Pat. No. 5,950,384.
U.S. Pat. No. 3,968,738
Inventor: William A. Matzke
Issued: Jul. 13, 1976
An assembly of plastic louver strips secured by two vertical frames having cut out portions into which the louver strips extend. Louver strips which are flexible can be snapped into place after the frame is in place. Flexible strips can also be removed for cleaning. The vertical frames are slidably assembled into basic frame members and when in place form a space into which the ends of the louvers are positioned.
U.S. Pat. No. 3,991,533
Inventor: Mitsuo Nagase
Issued: Nov. 16, 1976
A combination louver and window sash assembly includes a plurality of louver boards extending horizontally and each having a cross-section of substantially inverted-Y shape. A pair of parallel, vertical sash frames having vertically extending slots faced in opposed relation to one another and including pairs of cutout recesses formed in the marginal edges of the slots. The louver boards have their horizontal ends thrusted resiliently through the slots and received snappingly in the cutout recesses.

Issued: Jul. 13, 1976
A substantially rainproof louver for mounting in an outside wall of an enclosure. The louver has a perimeter frame and plurality of blades extending across the frame, the blades being upwardly inclined from the outer edges to their inner edges. Each of the blades has a gutter element extending along its outer, lower edge. The gutter element is defined by the lowermost portion of the blade, a vertical flange and a downwardly and inwardly inclined anti-splash lip at the upper edge of the vertical flange, the anti-splash lip overlying, at least in part, the lowermost portion of the blade and extending toward the blade.

Inventor: Robert W. Olsen
Issued: Jul. 13, 1976
A drainable blade louver comprises a pair of spaced-apart vertical members supporting a multiplicity of elongated, horizontally extending, inclined blades, each of which is of uniform cross section along its length. Each blade has an upwardly open front drainage trough located adjacent the front edge of the blade and at least one second upwardly open drainage trough located in at least about the front one-third of the blade closely adjacent the front trough. Each of the troughs is defined by spaced-apart front and back walls, the upper edges of which are preferably located in a plane substantially parallel to the airflow streams passing between the blades, and a bottom wall spaced a substantial distance below the upper edges of the front and back walls such that the splash from water drops impinging on the bottom walls of the troughs is largely confined to the zone bounded by the walls of the troughs thereby minimizing entrainment of water in the airflow streams.
U.S. Pat. No. 4,452,024
Inventor: James Sterriker et al.
Issued: Jun. 5, 1984
A louver in which some louver blades have water breaks for catching water that drops onto such louver blade from above. A top cap includes a lip portion which has an inwardly directed lower portion which directs water onto a louver located beneath the top cap.

Inventor: Kouichi Takano
Issued: Aug. 28, 1990
A louver device comprises a main body formed of a flexible sheet-like material. A large number of slits are formed in the main body such that the portions between the adjacent slits constitute slats. The louver device also comprises holding/deforming means for shearing at least part of the main body in the direction of the surfaces of the main body. The shearing force applied to the main body serves to twist the end of the slats, thereby slanting the slats.

The triangular shape of the louvers allow light to pass through the first and second color-tinted adjacent sides to add a soft color hue to a room. The third side of the triangular louver is opaque and acts much the same as does a common blind when used to block the light from entering a room. The third side may, however have a decorative scene or pattern on one it to present a pleasant scene to the onlooker. The third side has a rotation restriction and alignment tab on it to align the third sides of the louvers so that the decorative pattern or scene is clearly illustrated and that the louver is positioned to properly block the light. Each louver is removably attached to a support system in such a manner that the louvers may be rotated to allow light to pass through two of the adjacent sides and then be rotated so that the opaque third side is parallel to the window or door and restricts the passage of the light.
